How are cancers staged?

The clinical stage is an estimate of the extent of the cancer based on results of physical exams, imaging tests (x-rays, CT scans, etc.), endoscopy exams, and any biopsies that are done before treatment starts. For some cancers, the results of other tests, such as blood tests, are also used in clinical staging.

Is 3 cm tumor considered small?

Stage IA tumors are 3 centimeters (cm) or less in size. Stage IA tumors may be further divided into IA1, IA2, or IA3 based on the size of the tumor. Stage IB tumors are more than 3 cm but 4 cm or less in size.

How do you determine the size of a tumor?

Tumor volumes were measured bi-weekly and estimated by using the formula: Tumor volume= length x width2/2, where length represents the largest tumor diameter and width represents the perpendicular tumor diameter.

How is TGI calculated?

Tumor growth inhibition (%TGI) was determined twice weekly during the dosing period by the formula: %TGI = (1-{Tt/T0 / Ct/C0} / 1-{C0/Ct}) X 100 where Tt = median tumor volume of treated at time t, T0 = median tumor volume of treated at time 0, Ct = median tumor volume of control at time t and C0 = median tumor volume …
